Abstract
The increasing presence of toxic substances in
wastewater poses significant risks to environmental and human health,
necessitating the development of efficient remediation strategies. This study
aims to evaluate various adsorbent technologies for the effective removal of
hazardous contaminants such as heavy metals, dyes, and organic pollutants from
wastewater. We conducted a comprehensive review and comparative analysis of
conventional and novel adsorbents, including activated carbon, biochar,
metal-organic frameworks (MOFs), and nanomaterials. Experimental methods
involved batch adsorption tests, isotherm and kinetic modeling, and
regeneration performance assessment to determine adsorbent capacity,
efficiency, and sustainability. Results indicated that advanced adsorbents,
particularly MOFs and functionalized nanomaterials, exhibit superior adsorption
capacities and selectivity toward specific toxicants compared to traditional
materials. Furthermore, bio-based adsorbents demonstrated eco-friendly and
cost-effective potential for large-scale applications. Key findings emphasize the
importance of adsorbent surface modification and regeneration techniques in
enhancing performance and reducing operational costs. The study concludes that
integrating innovative adsorbent technologies with existing wastewater
treatment systems can significantly improve the removal of toxic substances,
promoting safer water reuse and environmental protection. Future research
should focus on scaling these technologies and addressing challenges related to
adsorbent recovery and disposal.
